This is a double-watch winder made of mahogany wood for added durability. It rotates your automatic watch to set direction and set Turns Per Day (TPD) to keep it wound. It has five different TPD settings: 650, 900, 1,200, 1,500 and 1,800, with intermediate rest cycles to eliminate potential stress on watch movement. It rotates clockwise, counter-clockwise or alternates in between. The winder will repeat its cycle every day as long as it is on, without intervention.
